Lv Zheng 7dd8821956 ACPICA: Events: Always modify GPE registers under the GPE lock 
It is reported that there are pieces of code invoking acpi_ev_finish_gpe()
without holding acpi_gbl_gpe_lock. Since this function will modify GPE
register values, there could be races breaking the register modification
process.

This patch fixes this issue. Lv Zheng.
